What is Tax Residency?
Tax residency determines where you must pay taxes. It depends on factors like where you live and work, varying across different countries and states, impacting how you handle income reporting and tax responsibilities.
Why is Tax Residency Important?
Knowing your tax residency is essential for accurate tax filings and preventing fines, especially for those working or investing in multiple jurisdictions.
Key Concepts
3 Different Types Of Tax Systems
There are primarily three tax systems: 1) Residential, 2) Citizenship-Based, and 3) Territorial.
Residential: Taxes residents on their worldwide income.
Citizenship-Based: Citizens taxed on worldwide income, regardless of residence. The U.S. and Eritrea use this system.
Territorial: Only taxes income earned within the country.
Residency vs. Domicile
Residency is where one lives at a particular time, whereas Domicile is considered the permanent home, the place one intends to return to after being away. Understanding the distinction is crucial as it impacts tax obligations and legal responsibilities.
Residency vs. Tax Residency
While residency refers to where one lives, tax residency is about where one is legally obligated to pay taxes. The criteria for determining tax residency can vary greatly by country and can be based on factors such as the amount of time spent in the country and employment status.
Tax Residency vs. Citizenship
Citizenship typically refers to the country where one was born or considered 'home'. In contrast, tax residence is where one is considered a resident for tax purposes, which can be influenced by various factors like the number of days spent in the country and substantial ties or 'substance' there.
Things To Consider
How is Tax Residency Determined?
Tax residency is primarily determined through two key factors: substance and the 183-day rule. Substance involves assessing meaningful connections like property, family, and financial activities within a country. Concurrently, spending over 183 days within a tax year in a country typically establishes tax residency, subjecting one to potential worldwide income taxation in that jurisdiction.
Multi State Tax Residency
Yes, under the right circumstances, you can be considered a tax resident in more than one jurisdiction. This is particularly relevant in the US, where temporarily working remotely or having substantial connections in multiple states could result in dual state residency. The key factor is often the 183-day rule, which, when applied, assesses whether your physical presence in a state meets the threshold for tax residency.
Local Source Income
Local source income refers to the income earned in a specific country and can lead to tax obligations in each country where income is generated, even if not a tax resident there. Awareness of these rules is key to maintaining tax compliance and avoiding penalties..
